Abstract

We report on the realization of novel instruments for absolute vapor pressure measurements: (i) a novel vacuum system in which the saturation vapor pressure of low-volatile substances can be measured directly and accurately, (ii) optomechanical “membrane sandwich” squeeze film pressure sensors with enhanced pressure response and pressure sensitivities on a par with those of the best commercial capacitive diaphragm sensors.
